Abstracts:

Experiments on the absorption of water vapor fixed aqueous lithium bromide (LiBr) a variable thickness circular ditch without surface-active substances and with varying concentrations of surfactant. To this end, the simulation has investigated the bottom topography and revealed the influence of variable flow layer thickness of fluid motion in the near-surface layer and heat-mass transfer process management capabilities. We investigated the structure of the solution in the subsurface layer, measure the temperature of the interphase surface with a thermal imaging camera. For a solution that does not contain surfactants is also calculating the force of surface tension. Shown that when injected into a solution of surfactants is a significant change in the structure of the flow in the subsurface layer, causing breaks in the film. Surface temperature measurement results of the surface obtained by means of a thermal imaging camera.
